Ah, I see what needs to be done.
Each object needs to have physics enabled:
// create player dummy object (CHANGE TO SPHERE LATER)
player_box = Model::Sphere();
player_box->SetPhysicsMode(Entity::CharacterPhysics.);
player_box->SetMass(1);
//player_box->SetFriction(0, 0
The only issues is that with these collisions, it seems that the player object is dragging along the floor, the interaction is slowing the player down, making it hard to move.
I figured I might have to be using Entity::RigidBodyPhysics instead of Entity::CharacterPhysics but that jus
